A .CORPORATION OF TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 752,885, dated February 23, 1904. Application led October lll, 1903. Serial No. 176,529. (No model.)

.To all whomfit'7nwy concern.-

Be it known that I, CHARLES S. CHAMPION, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-lWritingV Machines, of which the following is a specication.

My invention relates to type-writing machines, and more particularly to stop mechan- ,ism therefor.

In various characters of type-writing Work.- such, for instance, as in taking testimonyit is desirable at times to move the carriage beyond the point where it is normally arrested in order to Write within the margin, so that the characters Q 2l, XQ32-, or RDQ 46, for example, may appear within the margin.

The object of my invention is t0 provide efficient means which may be readily actuated to accomplish this result and to enable an operator to move the carriage beyond the point where it is normally arrested without occasioning further delay than is necessary to return the carriage. Y l

To the above and other ends, which will hereinafter appear, my invention consists in the various features of constructiom arrangements of parts, and combinations of devices to be hereinafter more fully described, and particularly set forth in the appended claims.

In the drawings, wherein like reference characters indicate corresponding` parts in the various views, Figure l is a plan view of a machine embodying my invention. Fig. 2 is an end elevation with parts broken away, showing the upper portion'of a machine with my improvements applied thereto. enlarged detail plan view of certainof the devices embodying my invention, the view illustrating the normal disposition of the parts except as to the locking-tooth. Fig. 4 is a like view of the same, showing the disposition of the parts when the carriage has traveled beyond the point where it is normally arrested. Fig. 5 is a detail perspective view of the devices shown in Figs. 3 and 4, and Fig. 6 is an enlarged detail perspective view of the locking devices to be hereinafter described.

Fig. 3 is an' I have illustrated my invention in its application to a No. 6 Remington type-writing machine, though it should be understood that the invention may be applied to various characters of Writing-machines and thatnumerous changes may be made to facilitate such application.

The top plate l of the machine has upwardlyextending supports 2I and 3, the former supporting a traverse-roda and the latter a traverse or guide rod 5. The platen-frame 6. is pivoted at Z to links 8,V which in turn are pivoted to a truck 9. The pivot-pins 7 eX- tend beyond their bearings and cooperate with set-screws` 10 and l1 to Vlimit the shifting movement of the platen-frame. The frame 6 supports a platen 12 and carries at the for- 'lever controls the line-spacing mechanism and is effective to actuate the carriage-release mechanism (not shown) in the usual manner. The truck 9 carries rollers 18, that are supported upon the` rod 4, and a rearwardly-extending arm 19 projects from the carriage, and its rear bifurcated end cooperates with a slidingA sleeve 20, that surrounds the traverse or guide rod 5. Supported between the upright supports 3 is the usual rack-bar or stop-rod 2l, which is graduated to correspond to the letter-space movements of the carriage in its travel from end to end of the machine. Extending rearwardly from the carriage is a margin-stop 22, which ordinarilyl cooperates with a suitable stop on the stop-rod-to limit the carriage in its movement from left to right.

So much of the machine as has thus far been described constitutes portions of the' vsliding sleeve 23, mounted thereon, and projecting forwardly from this sleeve or slide is a margin-stop 24, which extends into the path of' and' with which coperates the stop 22 on the carriage. The slide 23 has a locking device 25 pivoted thereto at 26, and said locking device is in the nature of a lever which has a spring 27 secured thereto, the free end of said spring bearing against a pin 28, that is carried by the slide. The free end of this lever-like locking device has an upwardlyextending pin 29 and a downwardly-projecting portion 30, from which a forwardly-extending tooth 31 projects. 4 The parts 30 and 3l are received within a slot 32 in the slide 23, and from an inspection of Fig. 3 it will be understood that the forwardly extending tooth 31 on the locking device is adapted to engage between the teeth 33 on the stop-rod and is normally maintained in such locking engagement by the spring 27. The slide 23 carries a forwardly-extending apertured ear 34, which receives a headed spindle 35, that is adapted to move freely through the aperture therein, and the right-hand threaded end of this spindle is received within a threaded opening in a lug 36 on a slide or stop 37. A coiled expansion spring 38 surrounds the spindle and bears-at one end against the part 36 and at its opposite end against the ear 34 on the slide 23, and the pressure of this spring is exerted to force the slides'23 and 37 away from each other. The slide 37 carries a spring-restored locking device 39, by means of which the slide is normally locked in engagement with the teeth 33 on the stoprod, but may be adjusted along the stop-rod with the slide 23 when desired. Extending upwardly from the slide 37 is a lug 40, which is apertured for the reception of a slide 41, that is headed at one end, 42, and has a cam 43 at the opposite end thereof. This slide is held in its adjusted position on the part 40 by a set-screw 43, the stem of which is received within a threaded opening in the part 40 and bears at its inner end against a side edge of the slide 41.

A lever or finger-piece 44 is pivoted at 16 to the forwardly extending ear 17 of the platen-frame and is maintained Vin its normal position by a spring 45. This lever has a rearwardly projecting crank finger 46, that coperates with the forward end of a lever 47, which is secured at its rear end to arockshaft 48, received in bearings 49 on the truck and fixed against longitudinal movement in said bearings. The inner end of the rockshaft 48 carries a rearwardly-extending crank- `arm 50, that has a cam 51 on the rear end thereof. This cam is located just to the right of the carriage-stop 22 and in its travel with the carriageis normally above the pin 29 on the locking device.

In the ordinary operation of the machine the movement of the carriage from left toyright will bring the margin-stop 22 on the .carriage into engagement with its coperating stop 24, and the slide 23 'being at this time locked to the stop-rod will arrest the carriage at the point determined by the position of the stop 24. This position may be changed by releasing the locking members 29 and 39 and moving both slides so that the stop 24 will be locked in a position where-it is desired to arrest the carriage. Should the operator desire to move the carriage beyond the point where it is normally arrested -by the stop 24, it is merely necessary to depress the lever 44, which causes an elevation of the forward end of the lever 47, and this results in rocking the shaft 48 and depressing the cam 51 so that in the travel of the carriage from left to right this cam will be brought into contact with the pin -29 on the locking device and will automatically release it from engagement with the teeth 33 on the stop-rod, as represented in Fig. 3. At about the moment when the locking device is released from the stop-rod, thus releasing the slide 23, the carriage-stop 22 engages the cooperating stop 24 on the slide and moves the slide toward the right with the carriage and against the tension of the spring 38. The initial movement of the slide 23 with the carriage toward the right brings the pin 29 above the highest portion of the cam 43 and to the rear of the edge 52 on the slide 41, as illustrated in Fig. 4. The movement of the slide 23 with the carriage may continue until the slide 23 is arrested by the fixed slide 37, when a further movement of the carriage to the right cannot take place. The operator proceeds to write within the margin, and in the continued movement of the carriage from right to left the slide 23 will follow the movement of the carriage, being pressed in that direction by the spring 38, and the locking device 25 at this time being held out ofengagement with the stop-rod by the controlling device 41. As soon, however, as the pin 29 passes the cam 43the locking device is forced by its spring 27 to rengage between the teeth of the stop-rod, and thus again automatically lock it in its initial position.

From the .foregoing description it will be understood that an adjustment of the part 41 determines the extent of movement that the slide 23 may make from right to left before it is locked to the stop-rod and that when the part'41 is secured in its adjusted position the slide 23 will always be automatically restored to and be locked in the same initial position duringY the return movement of the carriage' from its position beyond the point where it is normally arrested by the stops. This devIOO IOS

IIO

vice `therefore determines the distance that l rive letter-space distances beyond the pointy where it is normally arrested. If, on the other hand, the cam 43 is adjusted so that it will release the pin 29 when the slide 23 is at ten letter-space distances form the slide 37, then the slide 23 will be automatically locked at ten letter-space distances form the slide 27 and a movement of the carriage is aorded for -ten letter-space distances beyond the point lever 44, are provided to afford through thel travel of the carriage a movement thereof beyond the point Where it is normally arrested by bringing the cam 51 into contact with the locking device 25 and that the hand-controlled cam 51 is rendered effective by a movement of the carriage from left to rightto disengage the locking device 25 and to alford a receding movement or displacement of the stop 24 from its normal position and in the general direction of the travel of the carriage, so that the operator may Write Within the margin. Furthermore, it Will be seen that when the lever 44 is depressed the return movement of the carriage automatically brings about the unlocking of the locked stop and automatically brings about the receding or shifting movement of the unlocked or shiftable stop and that the movement of the carriage from right to left affords an automatic return of the unlocked stop and affords an automatic Vlocking thereof in the initial or normal position, or the position from Which it was moved.

The stop 24 may be regarded as an initial stop, since it is adapted to arrest the carriage at' the initial arresting-point during the nor- Ymal operation of the machine, and the stop 37 v maybe regarded as a nal stop, since it artion of a carriage, a stop on the carriage, a co-l operating stop on the frame of the machine,
